Description

Internet lore says that it's possible to share an SPI bus with an SD card and another device, as long as the SD card is initialized first.

User reports that the same error occurs when the SD card is initialized first. However, a full example in this order was not furnished as far as I saw.

If it's not a hardware impossibility, then it seems most likely the problem resides in the sd card code, perhaps failing to do "extra clocks" at the end of a transaction.

The recently added "CMD25" stuff does not seem relevant here, as the SD card is not being written in the example (and the problem is reported before the addition of CMD25).

Additional information

I am the one who opened this on the forum. I'm using the PyGamer with an Airlift ESP32 wing, which works fine with the sample code. Inserting an SD card (no code change) causes a "Timeout waiting for SPI char". Init the SD card causes the above error where it gets the wrong response. Simply eject the SD card and reload, the wifi works again.

jepler commented 2 years ago

I don't have quite the right hardware set-up, but I did find an airlift featherwing.

I put it together with a Feather Adalogger and a Feather M4 Express.

I've got CircuitPython 7.1.0-beta.1 loaded. My airlift version is old, 1.2.2, while you've got an up to date version.

Unfortunately, I'm not reproducing the problem yet. With or without the SD card inserted, the AirLift example completes OK. Even if I delete the lines to initialize the SD card and remove/re-insert it so it is not yet initialized into SPI mode.

Here's my full test program:

nuwaveit commented 2 years ago

Would it help if I provided my code file? It looks practically same as yours. I can also try to record a video of it working and not working.

Is there any diagnostics I can try on my end? I tried adding debug=True to the esp32 ctor, but really didn't add much value...

jepler commented 2 years ago

If you can, please test with a different SD card too.

nuwaveit commented 2 years ago

@jepler Different SD Card didnt make a difference. I copied your code from above, still gave the same output:

I am trying to reproduce this, I have a pygamer with an airlift featherwing, So far, ping @jepler code with the SDCard on SD_CS the Airlift works fine with or with out the card inserted BUT it is so far, unable to detect any SDCards..... still investigating

jerryneedell commented 2 years ago

After trying several different SDCards, I found one that works and it works OK with the airlift

I am unable to read many of my SDCards on this PyGamer... So far only the one works It is an 8Gbyte card -- not sure of the mauna. just says Micro Sd Ultimate 3.0 70MB/Sec

but to the original issue, the airlift works with it in or out.....

jerryneedell commented 2 years ago

hmmm -- if I switch to using the Adafruti_CircuitPythom_SD (adafruit_sdcard) library, I can read all of my SDCards.

jepler commented 2 years ago

adafruit_sdcard defaults to 1_320_000 as the SPI clock while sdcardio uses 8_000_000. You can try changing the frequency. (baudrate= in the constructor)

nuwaveit commented 2 years ago

if I do this: sdcard = sdcardio.SDCard(spi, sd_cs, baudrate=1320000) I get no sd card, and still the ESP32 errors...

gonna see if i can try the adafruit_sdcard lib...

nuwaveit commented 2 years ago

dhalbert commented 2 years ago

@nuwaveit Do you have any brand-name cards (e.g. Sandisk) that work? The sdcardio and adafruit_sdcard libraries use the slower SPI interface to cards, instead of the SDIO interface. We have found problems with a variety of cards.

nuwaveit commented 2 years ago

@dhalbert yeah, im using a newer Sandisk, and an older Kingston. I have a 3rd with no name on it but has the "microSD" logo...they all work when I insert the card, its the AirLift that gets knocked off...

jerryneedell commented 2 years ago

FYI -- I tried using baudrate=1320000 with sdcardio and it still fails to detect the card for me. Same card is fine with adafruit_sdcard.

This is a SanDisk 8G "Ultra" Class 10

nuwaveit commented 2 years ago

For the fact that I can consistently get this error sounds to me like there's a bug somewhere, maybe caused by a timing issue, or something is not getting reset...just my hunch...

File "adafruit_esp32spi/adafruit_esp32spi.py", line 335, in status ... RuntimeError: Expected A0 but got 80

jepler commented 2 years ago

I testedwith the above airlift setup all these cards, still using sdcardio. (see my full program listing above)

PXL_20211203_203941856

All passed, mounting SD and then doing the wifi fetch.

I had some cards appear to fail at first when I hot plugged them and then soft-restarted. All the cards worked when I fully power-cycled my testing rig (unplugged USB & plugged back in) -- the failure mode was "no sd card", after which the wifi portion of the test ran successfully.

I did similar tests using a TFT featherwing and an RP2040 Feather. All cards mounted fine there. This setup did not have an airlift featherwing so I didn't test the wifi portion there.

jerryneedell commented 2 years ago

¯\_(ツ)_/¯

nuwaveit commented 2 years ago

I didn't try it where I fully power off and unplug the USB to see if I can make the WiFi work with a mounted SD card. I will try once I'm back home.

But aside from that, what's the next step? It seems from @jerryneedell that his PyGamer rejected several SD cards as well, and I've tried 4 or 5 as well, all cause the WiFi to fail. Is there a way to raise this to the dev team that worked on PyGamer? I do not have any other device like the adalogger to compare...

jerryneedell commented 2 years ago

I have not been able to reproduce your finding on mine. It still fails to detect the cards even after power cycle when using sdcardio.

Also on my pygamer, I have not been able to reproduce the wifi issue reported by @nuwaveit

If there is a difference in how the SDCards mount after power cycle vs soft reboot, should consider this a "bug".

jepler commented 2 years ago

I only saw a problem when hot-plugging the SD card. If the SD card is inserted, it is fine no matter how many times I re-run the code.

jerryneedell commented 2 years ago

Ah -- that sounds better. It's hard to see why the pygamer should be different than any other SDCard reader. I have not seen this issue that I recall with other boards with SDCards. I'll try a few more configurations.

jerryneedell commented 2 years ago

I have reproduced the SDCard issue with a Feather M4 express and an adalogger featherwing using sdcardio

ah -- upgrading to latest CP now works with sdcardio on the feather m4 express.

jerryneedell commented 2 years ago

OK -- I give up -- I rebuilt CP for the Pygamer and now it is working with sdcardio on cards that had been failing.....

@nuwaveit Can you try with the latest build of CP from https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/pygamer/en_US/

use the 7.2.0 alpha build https://adafruit-circuit-python.s3.amazonaws.com/bin/pygamer/en_US/adafruit-circuitpython-pygamer-en_US-7.2.0-alpha.0.uf2

nuwaveit commented 2 years ago

Will do later tonight and report back. @jerryneedell

nuwaveit commented 2 years ago

OK, using the 7.2.0 alpha build didn't make any difference. I have 1 old SD that consistently won't read, but that's OK. All my other SDs read. The Wifi does not work no matter which card is in there, and no matter which SD library is used. But I did get slightly different errors at one point when testing with my SD cards out of my raspberry pis:

**RuntimeError: Expected A0 but got 9F**

The one below is interesting, because I usually got that error when the card was inserted, but did not actually initialize the SD card in code. But as you can see, its reading the card, but still throws the SPI timeout error.

is this related to #5688 ? Will this PR be merged into main?

dhalbert commented 2 years ago

We fixed #5600 with #5688, and that bug fix is now in "Absolute Newest". It's possible that fix will also fix the bug that some of you have reported in this issue. Could you try the "Absolute Newest" build if you have a chance to see if you still see the problem? Thanks.

@dhalbert @jerryneedell Sorry its been a long while, I just tried this version, still not working for me....still throws "Expected A0 but got 00" when checking esp.status...

While not specifically related to esp32spi I was having difficulty getting sdcardio to share a bus. Came across this issue via circuit python repo issue search. @jepler code did help. Was able to share SCK, MOSI, MISO with sdcardio and a SPI TFT. Each peripheral has its own CS pin. So can at least confirm the issue isn't the fault of sdcardio.

from circuitpython_st7796s import ST7796S

displayio.release_displays()
# 4.0" ST7796S Display
DISPLAY_WIDTH = 480
DISPLAY_HEIGHT = 320

tft_cs = board.D9
tft_dc = board.D10
tft_rst = board.D17
sd_cs = board.D5

spi = board.SPI()
# Initialize SPI SDCard prior to other SPI peripherals!
try:
    print("Attempting to mount sd card")
    sdcard = sdcardio.SDCard(spi, sd_cs) 
    vfs = storage.VfsFat(sdcard)
    storage.mount(vfs, '/sd')  
    print(os.listdir("/sd"))
except Exception as e:
    print("no sd card:", e)
    print("continuing")

display_bus = displayio.FourWire(spi, command=tft_dc, chip_select=tft_cs, reset=tft_rst)
display = ST7796S(display_bus, width=DISPLAY_WIDTH, height=DISPLAY_HEIGHT, rotation=180)

# System Stats
u_name = os.uname()
print("Board: ", u_name[4])
print("Type: ", u_name[0])
print("Version: ", u_name[3])

Code done running.

Ultimately in my case it was due to poor breadboard connections. I realize that doesn't apply if it's on a PCB but the successful SPI bus sharing with sdcardio might be helpful here.
